To date, funders of local projects have adopted the approach taken by their counterparts in Great Britain on similar projects, in that security has been sought in the form of a charge over the revenue stream generated by the unitary charge payable by the Authority to the Contractor. On certain projects, this has been supplemented by the requirement for a parent company guarantee and in most cases, the funders enter into direct agreements which provide additional comfort, including the right to step into ailing projects and assurances as to the performance of key sub-contractors. A small number of projects in Northern Ireland have been bond financed where funders have had the comfort of the role taken by the monoline insurers employing insurance programmes designed to pay out where the bonds fail. Monoline insurers typically require rigorous due diligence on the suite of project and finance documents. As bonds are generally suited to projects in excess of £100m, the local market is likely to see more projects financed in this way in light of the projects in the pipeline highlighted by the Investment Strategy for Northern Ireland published by the SIB.
